　　The cabinet frame adopts a 2mm thick high-strength cold-rolled steel plate (high-strength electrolytic steel plate or high-strength aluminum zinc coated steel plate can also be used according to user needs) welded frame structure, which has high strength and rigidity as a whole and is not easy to deform; The rack has good processing and assembly processability, handling performance, and good conductivity (grounding) performance. All components of the rack (including installation support parts) shall not undergo excessive deformation or damage under a load of more than 4 times the required installation weight. The resistance between the grounding points (screw holes, bolts) of the rack and the metal parts of the rack should be less than 0.01 ohms. Each grounding stud (hole) should be made of M8 copper or stainless steel. The top and bottom of the rack are designed with good installation and handling interfaces, and the interface fastening thread is M12. The upper and lower parts of the rack are respectively equipped with outlet ports that can meet the maximum configuration of the whole machine, and in principle, the power line and signal line should be separated for outlet. There should be a dedicated sleeve for protection at the fiber optic outlet. The upper part should have an interface connected to the cable tray; Modular holes are arranged at intervals of 25mm on the skeleton, making cabinet assembly convenient and exceptionally sturdy. The entire frame is precisely connected by horizontal and vertical bolts, and the frame structure is maintenance free.

　　2、充電模塊插框

　　2. Charging module plug-in frame

　　充電模塊的安裝部分采用了插框固定式結構，保證了充電模塊帶電插拔的配合精度，使帶電插拔操作可靠，同時也使柜體平面布局更加協調美觀；為避免因部件推拉安裝過程金屬表面滑動摩擦損傷而導致生銹，監(jiān)控模塊和充電模塊等推拉安裝式部件的滑動導軌采用不銹鋼材料。

　　The installation part of the charging module adopts a plug-in frame fixed structure, ensuring the precision of the charging module's live plugging and unplugging, making the live plugging and unplugging operation safe and reliable, and also making the cabinet layout more coordinated and beautiful; To avoid rust caused by sliding friction damage on the metal surface during the push-pull installation process of components, the sliding guide rails of push-pull installation components such as monitoring modules and charging modules are made of stainless steel material.

　　3、機柜前門

　　3. Cabinet front door

The installation plates of each device, side beams, and the inner and rear doors of the cabinet are all connected to the grounding copper busbar using galvanized copper conductive tape or multiple copper wires with a cross-sectional area of not less than 6mm2 to ensure good grounding.

　　6、的表面防護      機柜表面在經過嚴格的除油、除銹和磷化處理后，噴涂兩層底漆，并采用靜電粉體烤漆工藝完成表面噴塑。機柜防腐等級為戶內防中等腐蝕型：F1。機柜表面噴涂采用小皺紋塑粉，以滿足電力行業(yè)關于屏柜表面無反光、不耀眼的視覺要求。其塑粉不含有危險化學物質、鉛或其他重金屬，并具有、無臭、無污染及附著力強的優(yōu)點。涂層外觀色澤柔和、協調，質量優(yōu)異。

　　6. High quality surface protection cabinets undergo strict degreasing, rust removal, and phosphating treatment on their surfaces, followed by two layers of primer spraying and surface coating using electrostatic powder coating technology. The anti-corrosion level of the cabinet is indoor medium anti-corrosion type: F1. The cabinet surface is sprayed with small wrinkle plastic powder to meet the visual requirements of the power industry for non reflective and non dazzling screen cabinet surfaces. Its plastic powder does not contain hazardous chemicals, lead, or other heavy metals, and has the advantages of being non-toxic, odorless, pollution-free, and having strong adhesion. The coating has a soft and harmonious appearance, with excellent quality.

　　7、機柜的標準化、模塊化設計

　　7. Standardization and modular design of cabinets

　　目前公司對標準化、模塊化系數的初步要求是不小于70%，不過還應該根據產品客戶化要求的不同而有所區(qū)別。為達到較高的標準化、模塊化系數，應遵循以下一些通用準則：柜體外觀標準化，公司維諦EG110色（小皺紋灰白色）；柜體尺寸標準化，有800寬X600深X2260高（mm），600寬X600深X2260高（mm）兩種標準；機柜各單元模塊化,可將柜體分解成平行小裝配單元，盡量采用積木式結構，以利于提高生產率、降低工藝復雜程度。(一般可分解為交流單元、監(jiān)控單元、模塊單元、直流饋出單元、維護單元、防護單元等)。

　　At present, the company's preliminary requirement for standardization and modularization coefficient is not less than 70%, but it should also be differentiated according to the different customer requirements of the product. To achieve a high degree of standardization and modularity, the following general principles should be followed: standardization of cabinet appearance, the company recommends Weidi EG110 color (small wrinkles gray white); The cabinet size is standardized, with two standards: 800 wide X600 deep X2260 high (mm) and 600 wide X600 deep X2260 high (mm); Each unit of the cabinet is modularized, and the cabinet can be decomposed into parallel small assembly units, using a modular structure as much as possible to improve productivity and reduce process complexity. (Generally can be decomposed into AC unit, monitoring unit, module unit, DC feed out unit, maintenance unit, protection unit, etc.).

　　8、機柜方便的安裝維護和使用

　　8. Convenient installation, maintenance, and use of cabinets

　　為方便設備運行過程的維護和檢修，對裝有器件的機柜面板采用開啟靈活的內門形式，柜體內配有照明和單相交流220V電源插座。

　　For the convenience of maintenance and repair during the operation of the equipment, the cabinet panel equipped with components adopts a flexible inner door form, and the cabinet is equipped with lighting and single-phase AC 220V power sockets.

　　許多零部件的壽命較短，有的容易發(fā)生故障，在整個產品的壽命周期內需要多次更換，如保險裝置，防雷裝置、風扇、電源、光器件等，為更換損壞零部件而拆卸的零部件數量不超過2個（其中一個可能是蓋板、門等，另外一個可能是緊固件）;另一方面，有許多零部件在使用過程中需要清洗、檢查等例行的維護，如防塵網等。這些零部件的可拆卸性和可維護性符合以下規(guī)則：易損、易壞零部件、器件安排在比較明顯、容易更換的位置且用戶進行維護的零部件要采用易拆卸的裝聯方式，如卡接、插接(如接插件連接)、螺紋連接等，而避免采用半性連接或性連接方式。

　　Many components have a short lifespan and are prone to failure, requiring multiple replacements throughout the entire product lifecycle, such as safety devices, lightning protection devices, fans, power supplies, optical components, etc. The number of components disassembled to replace damaged parts should not exceed 2 (one of which may be a cover plate, door, etc., and the other may be a fastener); On the other hand, there are many components that require routine maintenance such as cleaning and inspection during use, such as dust nets. The disassembly and maintainability of these components comply with the following rules: vulnerable and easily damaged components, devices arranged in prominent and easily replaceable positions, and components maintained by users should use easily detachable assembly methods, such as card connections, plug connections (such as connector connections), threaded connections, etc., while avoiding semi permanent or permanent connections.

　　9、機柜邊框、棱角做光滑處理

　　9. Smooth the cabinet frame and edges

　　機柜的邊框、棱角以及任何可觸及的地方，不能有毛刺、尖銳棱邊等可能對操作者或線纜造成損壞的可能性。在裝配時，可能產生機械割刮傷的地方有：整機機柜的內外邊框，貼板名條棱邊，插框、部件著手的地方，電纜走線的走線槽或走線條以及靠近走線的棱邊，電纜進出線的進出線口等。我司柜體結構設計時考慮充分倒圓，或者增加卷邊以及使用噴砂等去毛刺措施。出線孔光滑，經充分倒圓或者采用翻邊的形式或者套防護套，以保證走線及維護操作。

　　The frame, edges, and any accessible areas of the cabinet must not have burrs, sharp edges, or any other potential damage to the operator or cables. During assembly, there may be mechanical cuts and scratches on the inner and outer frames of the machine cabinet, the edges of the nameplates, the places where the frames and components are handled, the cable trays or lines for cable routing, and the edges near the routing, as well as the cable entry and exit ports.
